  Purpose

This clinical trial studies the immune response after stem cell transplant in human immunodeficiency virus (HIV)-positive patients with hematologic cancer (blood cancer). Studying samples of blood from HIV-positive patients with cancer in the laboratory may help doctors learn more about changes that occur in the immune system after stem cell transplant.

Primary Outcome Measures:
  • Quantification of donor-derived HIV-1-specific immune responses following HCT [ Time Frame: Up to 1 year ] [ Designated as safety issue: No ]
    HIV-1 specific immune responses will be evaluated in samples collected before and after HCT. These results will be used descriptively.

  • Quantification of latently infected CD4+ cells in HIV+ patients [ Time Frame: Up to 7 years ] [ Designated as safety issue: No ]
    The overall measure of efficacy will be the log change in HIV-1 latent reservoir, measured as infectious units per million.


Estimated Enrollment: 10
Study Start Date: December 2009
Estimated Primary Completion Date: September 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment (HIV-specific immune reconstitution after HCT)
Patients undergo leukapheresis for analysis of HIV-1 latent reservoir at baseline and at days +90, +180, +365, and +730, and then annually thereafter as feasible.
Other: Laboratory Biomarker Analysis
Correlative studies
Procedure: Leukapheresis
Undergo leukapheresis
Other Names:
  • leukapheresis
  • Leukocytopheresis
  • Therapeutic Leukopheresis

Detailed Description:

PRIMARY OBJECTIVES:

I. Examine the development of donor-derived HIV-1-specific immune response following hematopoietic cell transplant (HCT) for treatment of hematologic malignancy in HIV+ patients.

II. Examine the affect of HCT on the pool of latently infected cluster of differentiation (CD)4+ T cells in HIV+ patients given HCT for treatment of hematologic malignancy.

OUTLINE:

Patients undergo leukapheresis for analysis of HIV-1 latent reservoir at baseline and at days +90, +180, +365, and +730, and then annually thereafter as feasible.
